LAM P-BURNER.

SPECIFICATION forming part of Letters Patent No. 564,991, dated August4:, 1896.

Application filed January 27, 1896, Serial No. 577,016. (No model.)

To aZ-Z whmn it may concern:

Be it known that I, J OSEPH GREGORY, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented a new and use-' ful Lamp-Burner, of which the following isa specification.

This invention relates to lam p-burners hav ing a central air-draft; andhas for its object to dispense with Wick-elevating mechanism of any kindand to prevent the breaking of lamp-chimneys, which frequently happensby the flaring of the flame, and to secure a maximum light and draft tosupport combus tion.

Other objects and advantages are contemplated and will appear as thenature of the invention is disclosed, and to this and such other ends aspertain to the spirit of the invention the latter consists in certaindetails of construction and combinations of the parts which hereinafterwill be more fully described, illustrated, and claimed.

The improvement is susceptible of various changes in the form,proportion, and l the minor details of construction Without departingfrom the principle or sacrificing any of the advantages thereof, and toa full disclosure of the invention an adaptation thereof is shown in theaccompanying drawings, in which- Figure 1 is a side elevation of a1a-rnp burner having the invent-ion applied. Fig. 2 is a verticalsection thereof on the line X X of Fig. 1. Fig. 3 is a plan section onthe line YY of Fig. 2. Fig. 4 is a side elevation of the wick-tube. Fig.5 is a side elevation of the extinguisher, having its operating-leverattached. Fig. 6 is a top plan view of the extinguisher and its lever.Fig. 7 is a detail view of the deflector.

Corresponding and similar parts are designated in the followingdescription and all the figures of the appended drawings by the samereference-characters.

The wick-tube 1 comprises an inner shell 2 and an outer shell 3 oflarger diameter and concentrically disposed, so as to provide an annularwick-space 4L between them. Torresponding openings 5 are formed in thesides of the shells 2 and 3, near their lower ends, and rings 6,extending across the Wick-space 4, have connection at their edges withthe said shells adjacent to the openings 5 in such a manner as toprevent the escape of any oil from the wick-space 4 into the openings 5.The lower end of the shell 3 is formed with an outer flange 7, whichsupports a base 8, perforated in its outer side for the entrance of airto support combustion. A jacket 9 is supported upon the base 8, and itsupper part is perforated for the admission of air exterior to thewick-tube. The gallery 10 is placed upon the jacket 9 and is providedwith holders 11 to retain the lamp-chimney in place.

The separator 12 is fitted within the upper portion of the wick-tube andhas its lower end 13 made conical and perforated, and its upper portionis contracted to form a neck 1-1 and is flared or expanded above theneck 1-1, as shown at 15, so as to properly spread the flame, and isclosed at its upper end by a plate 16. The upper part 14 and 15 isperforated to admit of the air escaping in finelydivided jets, so as tosupply the air to the flame in a uniform manner and to the best possibleadvantage.

A ring 17 of asbestos or mineral wool is fitted in the upper portion ofthe annular wickspace 4: and is practically indestructible, and can forthis reason he made thinner than a wick of cotton or other absorbentmaterial. In order to supply the ring 17 with oil from the fount orreservoir, a wicking or other absorbent material 18 is placed in thelower portion of the wick-tube and its lower end engages intimately witha disk or Wad 19 of some suitable absorbent material placed in the lowerportion of the Wick-tube and extending over a feeder 20, by means ofwhich the oil is supplied by capillary attraction to the absorbent disk19, thence to the wicking 1S, and to the ring 17, where the oil isburned. The feeder 20 is a tube, which extends into the fount orreservoir, and is provided on its inner side with a series of spurs orpoints 21, and wicking or other absorbent is forced into the tube 20 andretained in place therein by the said spurs or projections 21. Athreaded collar 22 is provided at the upper end of the tube 20 and isadapted to make connection with the ring or neck of a reservoir or fountin the usual way.

The extinguisher 23 is in the form of a sleeve and snugly fits the upperportion of the wicktube, and is slidably mounted thereon, and isprovided at diametrically opposite points with lugs 24, which areengaged by the operatinglever 25, so that when depressing the outer endof the said lever the extinguisher willbe moved upward to regulate theflame or extinguish it. The operating-lever 25 is formed of a length ofwire, which is doubled upon itself, so as to provide the handle 26, andthe end portions are oppositely curved, as shown at 27, to extend uponeach side of the extinguisher, and are recurved, forming springarms 28and folds 29, which latter receive the lugs 24:, and having the terminalportions 30 bent outwardly to provide journals, which engage with twoopenings of the perforated part of the jacket and which form the fulcrafor the said lever to tilt upon when operating the extinguisher. Byhaving the lever 25 constructed in the manner set forth the curvedmembers 27 will by reason of their elasticity press against the sides ofthe extinguisher 23 and retain the folded ends 29 in engagement with thelugs 24, and the spring-arms 28 will likewise maintain the journals orfulcra 30 in positive engagement with the openings in the said jacket.

In constructing and assembling the parts of the burner the ring 17 isadjusted so as to secure a maximum flame when the extinguisher is at itslowest position, and the parts are proportioned so that the flame willnot smoke or cause cracking or breaking of the chimney. Hence a savingin this item results from the use of a burner constructed in accordancewith this invention. To lower the flame, the projecting end:or handle 26of the lever 25 is depressed, thereby elevating the extinguisher untilthe flame or light is sufficiently reduced, and for extinguishing thelight the outer end of the lever is depressed until theupper end of theextinguisher comes in contact with the plate 16 or the perforated part15 of the separator.

In order to prevent interference of the draft entering the severalopenings 5 and direct the same upward through the wick-tube, a deflector31 is placed in the lower portion of the wick-tube and in the plane ofthe said openings 5, and is constructed to provide chambers 32 oppositeeach opening. For all practical purposes four openings 5 are sufficient,and I the deflector is formed of two plates intersectingniidway of theirlength and is placed so that the ends of the plates come between theopenings 5,.as shown most clearly in Fig. 3.

Having thus described the invention, what is claimed as new. is

1. In a central-draft lamp-burner, the combination with an annularwick-tube, of a separator fitted within the wick-tube and having itslower end pointed or conical, and having its upper portion contracted toform a neck and flared or expanded above the neck, the conical, neck andflared parts being perforated, and a plate closing the upper end of theseparator, substantially as described.

2. In a central-draft lamp-burner, the combination with an annularwick-tube having a series of draft-openings in its sides near the lowerend, and a deflect-or located in the plane of the said draft-openin gsand formed with inwardly-converging compartments or chambers oppositethe said draft-openings, of a separator located in the upper portion ofthe wick-tube and having its lower end pointed or made conical andperforated, the apex coming abovethe line of convergence of thecompartments of the deflector, and having a perforate neck and a flaringportion at its upper end, substantially as shown for the purposedescribed.

3. In a central-draft lamp-burner, the combination of an annularwick-tube having the lower end of the inner shell terminating above thelower end of the outer shell, a threaded collar having connection withthe lower end of the outer shell, a ring of indestructible absorbentmaterial fitted in the upper portion of the wick-space, an absorbentmaterial located in the lower portion of the wick-space and in contactwith the said absorbent ring, a disk or wad of absorbentmaterial at thebase portion of the Wick-tube and extending over and closing the upperend of the aforesaid collar and touching the absorbent materialimmediately thereabove at a point below the inner shell, and a feederhaving communication With the said absorbent disk or wad and fittedwithin the said threaded collar, substantially as and for the purposeset forth.

4. In a central-draft lamp-burner, the co1n-. bination with the wick,-tube, the jacket, and a tubular extinguisher slidably mounted upon thewick-tube and having lateral extensions, of alever for operating theextinguisher comprising a handle adapted to operate through the jacket,oppositely-curved members engagingwith the extensions of thetubularextinguisher, andarms having their terminal portions engaging with thejacket upon. opposite sides of. the handle and forming fulcra for thesaid lever, substantially as set forth.

In testimony that I claim theforegoing as myown I have hereto aflixed mysignature in the presence of two witnesses.
